Berkeley's Donkey & Goat Urban Winery

This year's Wine Expo in Sonoma County featured a seminar on Pét Nat, or Pétillant Naturel. It's an ancient method of making a sparkling wine with a single fermentation. It predates the more common methode champeniose that is used in Champagne and sparkling wine. On the panel was natural wine producer Jared Brandt of Donkey & Goat. He intrigued me. There's been a natural wine movement in recent years but Jared and his wife Tracey have been at it for over 2 decades. They rarely filter their wine and add as little sulfur as possible. He explains the reasoning behind that and his process as we hear their story.
